This review aims to provide a comprehensive synthesis of materials used in the fabrication of TMMs for MRI phantoms, focusing on their composition, fabrication methods, and relaxation properties (T1 and T2).</div></div><div><h3>Methods</h3><div>A systematic review was conducted, covering articles published between 1980 and 2023. Inclusion criteria encompassed studies involving physical MRI phantoms with measured T1 and T2 relaxation times. Exclusion criteria filtered out non-MRI studies, and digital/computational models.</div></div><div><h3>Results</h3><div>The review identifies and categorizes TMMs based on their primary gelling agents: agar, carrageenan, gelatin, polyvinyl alcohol (PVA), and other less common gels. Agar emerged as the most frequently used gelling agent due to its versatility and favorable MRI signal properties. Carrageenans, noted for their strength and minimal impact on T2 values, are often used in combination with agar. Gelatin, PVA, and other materials like Polyvinyl chloride (PVC) and PolyvinylPyrrolidone (PVP) also demonstrate unique advantages for specific applications. The review also highlights the challenges in phantom stability and the impact of various additives on the relaxation properties.</div></div><div><h3>Conclusion</h3><div>This synthesis provides a valuable guide for the fabrication of MRI phantoms tailored to desired T1 and T2 relaxation times, facilitating the development of more accurate and reliable imaging tools. Understanding the detailed properties of TMMs is fundamental to improve the quality control and educational applications of MRI technologies, especially with the advent of new magnetic field strengths and parametric imaging techniques.</div></div><div><h3>Implication for practice</h3><div>As experts in MRI systems, radiographers, educators, and researchers need to understand TMM compositions and methods of fabrications to develop MRI phantoms for educational tools and research purposes. This review serves as a valuable resource to guide them in these efforts.</div></div>","PeriodicalId":47416,"journal":{"name":"Radiography","volume":"30 6","pages":"Pages 1655-1668"},"PeriodicalIF":2.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142510303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
